Hydroelectric energy is transferred into usable energy by the moving water that flows through tunnels in a dam. As the water flows through the tunnels into the turbines, it drives the generators which produce electricity. This creates no pollution or waste and is a efficient way to produce. The electricity transfers to houses and business factories. It is used everyday by millions of people.
Hydroelectricity is used today by the Hoover Dam in Chicago. Also by homes for their electricity and its also used by businesses to run their factories. Every single dam also produces and uses hydroelectricity. http://www.pbs.org/wgbh/americanexperience/films/hoover/ Advantages:
no waste or pollution
very reliable
can be generated constantly all day
water can be stored in dams or other lakes, rivers, etc.
